Description
Technical field
The present invention relates to a kind of gasoline composition and preparation method thereof, relate in particular to a kind of high-octane gasoline composition and preparation method thereof.
Background technology
The interpolation component of the octane value of traditional raising gasoline mainly is lead-containing compounds, but owing to the severe contamination of lead-containing compounds to environment, country has prohibited the production doped fuel.Now can be by in gasoline, adding the octane value that arene compounds, oxygenatedchemicals or methyl cyclopentyl-dialkyl-tricarbon manganium (MMT) improve gasoline.
Oxygenatedchemicals commonly used mainly comprises ether based compound and pure based compound, and wherein the ether based compound comprises methyl tertiary butyl ether (MTBE), Ethyl Tertisry Butyl Ether (ETBE) and tertiary amyl-methyl ether (TAME).The most frequently used in the above-mentioned ether based compound is MTBE, but MTBE exists the solubleness of following shortcoming: the one, MTBE in water to be about 4.2 weight %, and MTBE has unpleasant stink, when the content in water surpasses 40-95pg/L, will make the water generates niff; In a single day the 2nd, MTBE is difficult to biological degradation, thereby is mixed with the gasoline leakage of MTBE, MTBE just will remain in the environment for long periods.In view of MTBE causes severe contamination to soil and tap water easily, in the city clean gasoline standard that will implement future, the add-on of MTBE has been done restriction, the amount of MTBE should not surpass 15 weight % in the regulation gasoline.For pure based compound, based on methyl alcohol, ethanol and the trimethyl carbinol, but pure based compound is water-soluble very high, meets water and easily separates with gasoline, and motor performance is caused negative impact, and therefore the use of pure based compound is restricted to a certain extent.Because the aromatic hydrocarbons based compound causes negative impact to environment easily, therefore, the addition of aromatic hydrocarbons based compound in gasoline also has strict restriction.
In addition, methyl cyclopentyl-dialkyl-tricarbon manganium (MMT) also is at present domestic a kind of gasoline dope relatively more commonly used.MMT a kind ofly can improve gasoline octane rating lead-free efficient lead-less gasoline antiknock dope again.The addition of MMT is few and cost is low, therefore is subjected to users' favor.But the products of combustion of MMT can form settling at the sparking plug of engine, makes the combustion conditions variation; MMT sees that light easily decomposes, and causes the octane value in the gasoline use to reduce.The produced simultaneously manganese waste gas that contains causes severe contamination to environment, and present most of developed country has banned use of MMT.Also clearly the manganese content of regulation motor spirit is not more than 0.016g/L to the national phase III vehicular emission standard (that is state III standard) of China's reality row.
At present, people also begin to pay close attention to the ester based compound as the application of the interpolation component of the octane value that improves gasoline.
CN1198466A discloses a kind of composite additive for gasoline and production method thereof, and this composite additive for gasoline is formulated by the dyestuff of the solvent of the Viscotrol C of the organic acid anhydride of the enzyme of the aromatic hydrocarbons of the ester class of the halo ethane of the haloolefin of the cyclopentadiene of 0-5.0 weight %, 0.4-1.6 weight %, 0-1.5 weight %, 0.3-4.0 weight %, 30.0-65.0 weight %, 0-5.0 weight %, 1.0-5.0 weight %, 0-10.0 weight %, 30.00-60.0 weight % and 0.001-0.02 weight %.Wherein, the general formula of described ester class is C
xCOOC
y(wherein, x is the integer of 1-4, and y is the integer of 1-3), can be for being selected from one or both the mixture in ethyl acetate, propyl acetate, butylacetate, dimethyl malonate, the diethyl malonate etc., wherein, the blending ratio of two kinds of esters is generally 1: 1-1: 3.Although this compositions of additives can improve the octane value of gasoline,, the content of aromatic hydrocarbons is very high in this compositions of additives, and therefore, the raising of gasoline octane rating has benefited from the aromatic hydrocarbons that adds in fact; And because aromaticity content is higher, this compositions of additives is difficult to satisfy the environmental protection standard of increasingly stringent.In addition, the complicated component of this composite additive for gasoline, blending process is loaded down with trivial details, also is unfavorable for reducing cost.
CN1513954A discloses a kind of multifunctional fuel and production method thereof, and the raw material of this multifunctional fuel comprises body material and auxiliary material two portions.Wherein, body material comprises: lighter hydrocarbons, lightweight oil, another name for, sulphonated oil, coal tar, gasoline and diesel oil; Auxiliary material comprises Ethyl Stearate, potassium permanganate, sodium hydroxide, water, ethanol, hydrogen peroxide, ethyl naphthol, sherwood oil, cyclopentadiene iron, acetone, toluene, phytic acid, sec-butyl acetate, butyl valerate, isopentene, vinyl acetic monomer, Losantin, sodium tetraborate ten water, 2 phenylethyl alcohol and pimelinketone.Above-mentioned auxiliary material is formed A, B, C, D four assembly sides, the effect that produces solubility promoter, oxygenation agent, ignition dope, smoke suppressor, antidetonation detonation suppressor, static inhibitor, sanitas and alkane value conditioning agent by chemical reaction respectively.Wherein, the proportioning of each assembly side is as follows:
A group: Ethyl Stearate 2-20 weight %, potassium permanganate 3-15 weight %, sodium hydroxide 2-15 weight %, water 40-80 weight %, ethanol 5-30 weight %;
B group: ethyl naphthol 5-25 weight %, sherwood oil 10-30 weight %, hydrogen peroxide 5-20 weight %, cyclopentadiene iron 5-30 weight %, acetone 3-30 weight %, toluene 5-30 weight %;
C group: phytic acid 5-25 weight %, sec-butyl acetate 3-30 weight %, butyl valerate 5-30 weight %, isopentene 10-40 weight %, vinyl acetic monomer 5-20 weight %, Dyhard RU 100 5-40 weight %;
D group: connection hexahydroaniline 2-20 weight %, Losantin 3-30 weight %, sodium tetraborate ten water 5-35 weight %, 2 phenylethyl alcohol 5-50 weight %, pimelinketone 5-30 weight %, polyene-based succimide 5-35 weight %.
Cross reaction by above four assembly square tubes and be mixed with composite additive E group, as required the E group is added to react in the major ingredient to being mixed with multifunctional fuel then.Though this multifunctional fuel has been used sec-butyl acetate, but sec-butyl acetate is added in this multifunctional fuel as just a kind of auxiliary agent, and the addition of sec-butyl acetate is very low, and wherein, the addition of sec-butyl acetate in this multifunctional fuel is less than 0.5 weight %.And, when although CN1513954A also specifically discloses the production gasoline engine fuel, No. 120 solvent oils of the another name for of No. 70 gasoline of 50 weight parts, 30 weight parts, 20 weight parts E group composite additive with 0.45 part can be mixed, but the specific performance index of this gasoline engine fuel of unexposed preparation also.
The subject matter of the disclosed fuel oil additive of CN1513954A is: the composition of fuel dope is many, therefore, the blending process complexity, cost is too high; And A, B, C, D four assembly Fang Jun contain the olefines material, and the content of olefines material is all higher, is unfavorable for reducing the olefin(e) centent of gasoline, thereby not environmental protection.
EP0905217A discloses a kind of white gasoline, and this white gasoline contains the oxygenatedchemicals that carbonatoms is 2-15, and the feasible total amount with gasoline of the content of described oxygenatedchemicals in gasoline is benchmark, and the content of Sauerstoffatom is 0.1-15 weight %.The introducing of described oxygenatedchemicals can reduce the exhaust smoke level of engine, and the inhibition sparking plug is smouldered and reduce the carbon deposit that gasoline forms in the combustion chamber.Although specifically disclosing described oxygenatedchemicals, EP0905217A can be the ester based compound, but, embodiment only discloses the gasoline that contains methyl tertiary butyl ether, tertiary amyl ethyl ether and methoxy propyl yl acetate respectively, and the disclosed also not significant raising of octane value that contains the gasoline of methyl tertiary butyl ether, tertiary amyl ethyl ether and methoxy propyl yl acetate respectively.
GB2114596A discloses a kind of fuel composition, and this fuel composition contains the tert.-butyl acetate of 3-50 volume %; And the fuel composition of the tert.-butyl acetate of the gasoline that contains 90 volume % and 10 volume % specifically disclosed, research octane number (RON) and the motor-method octane number of this fuel composition all increase than feed gasoline, but, tert.-butyl acetate is as product in the middle of a kind of chemical industry of top grade, the price comparison costliness, also uneconomical as the interpolation component of gasoline.
In sum, exploitation has high octane value, long inductive phase, low gum level, toxicological harmless and cheap gasoline dope, thereby environmental protection, the anti-knocking property that improve gasoline are efficiently just becoming the research topic that becomes more and more important.

Embodiment
Gasoline composition according to the present invention contains feed gasoline and sec-butyl acetate, and in the total amount of described gasoline composition, the content of described sec-butyl acetate is 1-30 weight %, and the content of described feed gasoline is 70-99 weight %.
Sec-butyl acetate is a kind of water white liquid, and is water insoluble, but can be dissolved in most organic solvents.The present inventor is a kind of good gasoline dope through discovering that sec-butyl acetate has the excellent comprehensive performance.Be described in detail below in conjunction with the correlated performance index.
1, density
The density of motor spirit is generally 0.70-0.78kg/m
3, the density of sec-butyl acetate is 0.862kg/m
3, be not more than at addition under the condition of 30 weight %, add sec-butyl acetate and can not cause detrimentally affect to the density of motor spirit.
2, octane value and anti-knock index
Octane value is an important index weighing the motor spirit anti-knocking property, also is an important indicator weighing gasoline dope.
Motor-method octane number and research octane number (RON) when following (octane value 100 or 100) all are under standard conditions, and the tendency to detonate of the reference fuel of sample and known octane value is compared.Reference fuel is mixed by octane-iso (octane value is 100) and normal heptane (octane value is zero), and the percent by volume of contained octane-iso in the reference fuel suitable with the knock intensity of sample is exactly the octane value of this sample.Wherein, motor-method octane number is measured by the regulation of GB/T503, and research octane number (RON) is measured by the regulation of GB/T5487.
The measuring method of research octane number (RON) and motor-method octane number with and equipment basic identical, different standard conditions differences when just measuring.(severe condition of 900r/min ± 10r/min) are feature to motor-method octane number, generally the anti-knocking property of gasoline when being determined at the running of engine air throttle standard-sized sheet and high engine speeds with higher mixture temperature (generally being heated to 149 ℃) and higher motor speed.Then (the medium severe condition of 600r/min ± 6r/min) are feature to research octane number (RON), generally the anti-knocking property of gasoline when evaluating engine and carry out the transition to the middling speed operation by low speed with lower mixture temperature (generally not heating) and lower motor speed.Generally than motor-method octane number height, available following relationship is similar to both numerical value of conversion, that is: with a kind of Study of Gasoline method octane value
Motor-method octane number=research octane number (RON) * 0.8+10.
The difference of research octane number (RON) and motor-method octane number is called susceptibility of gasoline.
Sec-butyl acetate has very high octane value, and wherein, research octane number (RON) (RON) reaches 119, and motor-method octane number (MON) reaches 107, apparently higher than component or the additive (table 1) of the octane value of raising gasoline commonly used.
Table 1
| Project | Reformed gasoline | Heavy aromatics | Butene alkylated oil | Ethanol | Methyl alcohol | T-butyl methyl ether | Ethyl Tertisry Butyl Ether | Methyl tertiary butyl ether | Sec-butyl acetate |
| MON | 88.2 | 94.0 | 95.9 | 96 | 98 | 98 | 102 | 99 | 107 |
| RON | 100.0 | 107.0 | 97.3 | 111 | 114 | 111 | 118 | 117 | 119 |
Motor-method octane number and research octane number (RON) all are on special single-barrel engine, measure under standard test condition, are difficult to reflect the capability of antidetonance of fuel under the vehicle operating condition comprehensively.Therefore, proposed to calculate the empirical relationship of the capability of antidetonance under the vehicle actual motion condition, that is:
Anti-knock index=(RON+MON)/2
Adopt anti-knock index to reflect the average capability of antidetonance of gasoline under the general operational requirement.By following formula as can be known, the octane value of gasoline is more high, and its anti-knocking property are just more good, and the dynamic property of engine and economy just more can embody.The anti-knock index of sec-butyl acetate is 113, also the anti-knock index of the gasoline dope of listing in the table 1.
3, boiling range
Vapo(u)rability is one of most important characteristic of gasoline.Gasoline enters before the engine cylinder, at first rapidly gasification and form inflammable mixture with air in vaporizer.Generally speaking, the residence time of gasoline in inlet pipe has only 0.005-0.05s, and the evaporation time in cylinder also has only 0.02-0.03s.Form uniform inflammable mixture in the so short time, except the structure and operational condition of petrol motor, main factor is the vapo(u)rability of gasoline itself.The index of the volatility of reflection gasoline is boiling range and saturation vapour pressure.In the quality standard of China's motor spirit, the boiling range index comprises 10 volume % vaporization temperatures, 50 volume % vaporization temperatures, 90 volume % vaporization temperatures and final boiling point (that is, doing).
(1) 10 volume % vaporization temperature
What of low boiler cut that gasoline contains are 10 volume % vaporization temperatures represent, the difficulty or ease of gasoline engine starting are had decisive influence, simultaneously, also with the tendency that produces vapour lock close relationship arranged.10 volume % vaporization temperatures are more low, show that the low boiler cut that contains in the gasoline is more many, vapo(u)rability is more strong, make petrol motor be easy to start at low temperatures; But if this vaporization temperature then is easy to generate vapour lock low excessively.Require the vaporization temperature of 10 volume % not to be higher than 70 ℃ in China's motor spirit quality standard.
(2) 50 volume % vaporization temperatures
50 volume % vaporization temperatures are represented the average volatility of gasoline, with the length of heating-up time behind the gasoline engine starting and accelerate whether in time all to have substantial connection.50 volume % vaporization temperatures of gasoline are more low, and the steam output under normal temps is also just more big, thereby can shorten the heating-up time of petrol motor, simultaneously, also can make engine accelerate sensitive, running is soft.If 50 volume % vaporization temperatures are too high, when engine need be transferred at a high speed by low speed, when fuel delivery sharply increases, most of gasoline can not gasify, and causes incomplete combustion, when serious even can be flame-out suddenly.Require 50 volume % vaporization temperatures not to be higher than 120 ℃ in China's motor spirit quality standard.
(3) 90 volume % vaporization temperature and final boiling point
What of heavy ends content in the gasoline 90 volume % vaporization temperatures and final boiling point represent.If this temperature is too high, illustrate that to contain heavy ends in the gasoline too much, be difficult for guaranteeing gasoline evaporation and perfect combustion fully under working conditions.This will cause incrustation of cylinder to increase, and specific fuel oil consumption rises; Evaporate incomplete gasoline heavy ends simultaneously and also can flow into crankcase, thereby lubricating oil dilution is added galling.Require 90 volume % vaporization temperatures not to be higher than 190 ℃ in China's motor spirit quality standard, final boiling point is not higher than 205 ℃.
The boiling point of sec-butyl acetate is 112.3 ℃, and have certain volatility, and to add in the gasoline, 10 volume % of gasoline and 50 volume % vaporization temperatures slightly rise, 90 volume % vaporization temperatures slightly descend, and can not produce negative influence to the volatility of gasoline composition.
4, residual quantity
The residual quantity of gasoline also is an important factor of direct reaction gasoline quality, the oxidation jelly content that generates in least evaporable heavy ingredient and the storage process in its expression gasoline how much.Residual quantity index height can make combustion chamber and valve assembly carbon deposit increase, and inlet system and carburetor throat gum deposit are serious, thereby influence the works better of engine.State III standard code residual quantity is not more than 2%.The basic noresidue amount of sec-butyl acetate can not produce negative influence to the residual quantity of gasoline composition.
5, saturation vapour pressure
Under prescribed condition, oil product is in suitable testing apparatus, and when gas-liquid two-phase reached balance, the shown peak pressure of liquid level steam was called saturation vapour pressure.Saturation vapour pressure is used for evaluating the evaporation capacity of gasoline, is to weigh whether gasoline is easy to generate vapour lock in the petrol motor fuel feed system index, can also weigh the loss tendency of gasoline in storing transportation simultaneously.The saturation vapour pressure of gasoline is more big, and vapo(u)rability is also just more strong, and engine is easy to cold start-up, but produces the tendency increase of vapour lock, and vapour loss is also more big.Therefore, barometric point and envrionment temperature are not simultaneously, and be different to the requirement of the saturation vapour pressure of gasoline yet.State III standard code gasoline vapour pressure was not more than 88kPa from April 30 November 1 to next year, was not more than 72kPa on the 31st from May 1 to October.
Sec-butyl acetate is added in the gasoline, and the saturation vapour pressure of gasoline slightly descends, but influences lessly, can make the gasoline that contains sec-butyl acetate meet national standard fully.
6, inductive phase
Induce index futures under the promote the oxidation condition of regulation, oil product is in the time cycle that steady state experiences, and can measure according to the method for GB/T8018 regulation.The method summary is: sample is oxidation in oxygen bomb, and this oxygen bomb elder generation to 68gkPa, is heated to 98 ℃-102 ℃ 15 ℃ of-25 ℃ of following oxygenations then.The timed interval is in accordance with regulations read pressure or continuous recording pressure, until arriving weight break point.The sample arrival needed time of weight break point is the actual measurement inductive phase under the test temperature.Survey the inductive phase in the time of just can calculating 100 ℃ inductive phase thus.Induction period of gasoline in minute.Obviously, induction period of gasoline is long, and then the tendency of oxidation and formation colloid is just little.State III standard code induction period of gasoline is not less than 480 minutes.Satisfied the index of state III greater than 600 minutes the inductive phase of sec-butyl acetate.
7, water soluble acid or alkali
Water soluble acid refers to mineral acid and low molecular organic acids, and water-soluble alkali refers to sodium hydroxide etc.They generally left behind in petroleum refining process, and metal is had strong corrosive nature, do not allow in the gasoline to exist.Can be according to the content of water soluble acid or alkali in the regulation mensuration gasoline of GB/T259.The method summary is: with water soluble acid or the alkali in distilled water or the aqueous ethanolic solution extracting sample, then, check Extract change in color situation with tropeolin-D or phenolphthalein indicator respectively, or measure the pH value of extract with acidometer, have or not existing of water soluble acid or alkali with judgement.The substantially anhydrous dissolubility acid of sec-butyl acetate product does not contain water-soluble alkali yet, meets relative national standards.
8, mechanical impurity and water
The gasoline product that refinery is refined out is not contain mechanical impurity and moisture, but in accumulating and use, gasoline is subjected to outside contamination inevitably, makes mechanical impurity and moisture enter in the gasoline.Mechanical impurity in the gasoline might stop up carbureter jet and gasoline filter; Also can aggravate simultaneously the wearing and tearing of carbureter jet, cylinder-piston assembly.Moisture in the gasoline then may freeze in the winter time, can stop up purifier or oil circuit when serious, even cause oil failure; In addition, moisture accelerates the parts corrosion in addition, and dissolving oxidation inhibitor accelerates the gasoline oxidation rubber, and causes that tetraethyllead decomposes, and makes undesirable actions such as additive inefficacy such as deriving agent.Checking in the gasoline whether contain mechanical impurity and moisture, generally is sample to be annotated leave standstill mechanical impurity and the moisture that should keep transparent behind the 8-12h and not have suspension and sedimentation in the glass cylinder of people 100mL.When having objection, mechanical impurity can be measured by the method for GB/T511 regulation; Moisture can be measured by the method for GB/T260 regulation.Through measuring, there is not mechanical impurity and the moisture of suspension and sedimentation in the sec-butyl acetate.
9, aromaticity content
No aromatic hydrocarbons produces in the production process of sec-butyl acetate, so the aromaticity content of sec-butyl acetate product is 0.
10, olefin(e) centent
Stipulate in the motor spirit quality standard that the content of alkene should be less than or equal to 30 volume %.Although there is a spot of olefines material to produce in the production process of sec-butyl acetate, olefin(e) centent is lower, can not significantly improve the olefin(e) centent of gasoline.
11, oxygen level
Oxygen level in the restriction motor spirit mainly is to consider the problem of calorific value, and oxygen level increases in the gasoline, and the effective constituent that then can burn in the gasoline reduces, thereby calorific value is reduced, and influences the power of engine.In addition, too high oxygen level in the gasoline, the carbon deposit in the cylinder can be fewer and feweri, and the inblock cylinder valve loses the carbon deposit protection, and then wearing and tearing can be more serious.In existing motor spirit standard, the oxygen level in the gasoline should be lower than 2.7 weight %.Although the oxygen level of sec-butyl acetate is 27.6 weight %, can make the gasoline that contains sec-butyl acetate satisfy the regulation of motor spirit standard by the addition of control sec-butyl acetate in gasoline.
12, iron level
Do not use iron equipment in the production process of sec-butyl acetate, so also iron content not of sec-butyl acetate product.
13, existent gum
Existent gum is used for generally illustrating that gasoline may generate sedimental tendency on intake ducting and intake valve, is the part that is insoluble to normal heptane in the gasoline residue on evaporation that records under prescribed condition.Can measure according to the regulation of GB/T8019, the method summary is: the fuel of known quantity is evaporated under control temperature and control conditions of air, with before the normal heptane extracting and extracting after residue weigh respectively, gained is the result report with mg/100mL, just can record the gasoline existent gum.Existent gum when state III standard code gasoline dispatches from the factory is not more than 5mg/100mL.The existent gum of sec-butyl acetate is 0.5-1.2mg/100mL only, satisfies the regulation of state III standard.
14, doctor's experiment
The doctor test refers in the presence of sublimed sulphur, with sodium plumbite and oils effect, and to check mercaptan in the oil or the test of hydrogen sulfide, can be according to the method mensuration of SH/T0174 regulation.Doctor test's method principle is: 10mL sample and 5mL doctor solution are put into the 50mL graduated cylinder of being with grinding port plug, firmly shake.If the sample sulfide hydrogen then generates the lead sulfide of black.As do not have above-mentioned reaction, then add a little pure and dry powdery sublimed sulphur again, and shake again.If have mercaptan in the sample, through series reaction, can cause oil reservoir and sulphur film change in color.By test, sec-butyl acetate is tested by doctor.
15, copper corrosion (50 ℃, 3h)
